Anthropogenic Edges, Treefall Gaps, and Fruit–frugivore Interactions in a Neotropical Montane Forest
In a montane tropical forest in southwestern Colombia, we investigated how anthropogenic edges may alter bird-mediated seed dispersal from edge to forest interior as a function of edge age and presence of treefall gaps. We estimated fruit abundance and mist-netted birds at four distances from edge to forest interior (0–10, 30–40, 60–70, and 190–200 m) in three young (,12 yr) and three old (.40 ...
متن کاملWidespread Forest Vertebrate Extinctions Induced by a Mega Hydroelectric Dam in Lowland Amazonia
Mega hydropower projects in tropical forests pose a major emergent threat to terrestrial and freshwater biodiversity worldwide. Despite the unprecedented number of existing, under-construction and planned hydroelectric dams in lowland tropical forests, long-term effects on biodiversity have yet to be evaluated. We examine how medium and large-bodied assemblages of terrestrial and arboreal verte...
متن کاملVariability of Carbon and Water Fluxes Following Climate Extremes over a Tropical Forest in Southwestern Amazonia
The carbon and water cycles for a southwestern Amazonian forest site were investigated using the longest time series of fluxes of CO2 and water vapor ever reported for this site. The period from 2004 to 2010 included two severe droughts (2005 and 2010) and a flooding year (2009). The effects of such climate extremes were detected in annual sums of fluxes as well as in other components of the ca...
متن کاملBioinvasion in a Brazilian Bay: Filling Gaps in the Knowledge of Southwestern Atlantic Biota
BACKGROUND Biological invasions are a major cause of global species change. Nevertheless, knowledge about the distribution and ecology of introduced species is regionally biased, and many gaps in knowledge exist for most developing countries. METHODOLOGY/PRINCIPAL FINDINGS To study the zoobenthos on the hard substratum of the Ilha Grande Bay, a survey was conducted on both natural and artific...
متن کاملBlood parasites in passerine birds from the Brazilian Atlantic Forest.
Parasites may lead bird species to extinction, affect host temporal and spatial population dynamics, alter community structure and alter individual' social status. We evaluated blood parasite prevalence and intensity according to bird families and species, among 925 birds that were caught in 2000 and 2001, in the Atlantic Forest in the State of Minas Gerais, Brazil. We applied Giemsa staining t...
